The x402 marketplace.

The open index of paid APIs for agentic commerce - 2,820 independent sellers on Base alone besides this host, with what they charge and, on Base, what they have actually settled.

Describe the job, not the tool name - FIND searches every tool and shows live results. Resolving is free (GET /api/find), you only pay to execute. This is the neutral x402 index: every seller, not just ours.

Agent402 runs this index and sells 500+ tools, metered models and reports on the same rails. These figures count paid settlements from outside buyers only: our own canary and volume runs and free proof-of-work calls are left out. The ranked rows measure other sellers on chain and never include the host. Settlements are counted from the sales ledger, which starts 2026-07-03; earlier calls were served and settled but are not itemised in it, so these are not lifetime totals.

tools → why pay here → every settlement →

healthy = the last crawl of the origin succeeded, nothing more. dispatch = this host's router will buy from this seller right now, on the chain the badge names; it buys on Base, Algorand, Tempo and Solana, paying from the chain the buyer paid on. A seller can be listed, healthy and still not dispatch-eligible (for example: the last crawl failed, it accepts no chain the router pays on, or it has too little settlement history yet). The reason is on each row and on /api/index as routerDispatchReason.

Every seller, every chain

THIS HOST = run by agent402 · every other seller is independent, found by the open crawl · Chain shows the networks each seller's 402 advertises · tx = settled calls on Base, last 7d, from the seller leaderboard

Describe the task and the Smart Order Router resolves it to a tool - from this index, ours or anyone else's - then runs it. Candidates are ranked by how well they match, then crawl health, buyers and price; a model can make the final pick (the full rule). It buys from external sellers and resells the result to you.

HOW THE INDEX IS BUILT

Crawled, not curated

01Discovery: the x402 Bazaar discovery listing plus our own crawler, plus anyone who self-registers at POST /api/index/register.
02We read each seller's manifest for its tools, routes and prices, and its live 402 challenge for the chains it accepts.
03A probe every 30 minutes records whether the manifest and challenge still respond. Probes are never paid calls.
04Rolling health feeds the Smart Order Router, which breaks ties on health rather than price alone and routes around sellers that are down.

No editorial gate and no pay-for-placement. A row can be corrected or withdrawn on request (see below), and a seller that stops answering is marked unreachable.

Add your API to the index.

Free, no signup, nothing deducted. Serve a 402 and register the origin: the crawler reads it at once and re-probes it every 30 minutes.

About this index.

What is an x402 marketplace?

A directory of services that accept x402 payments, so an AI agent can find something to buy and pay for it in one round trip without an account. This index lists every seller it can crawl, not only our own tools, and publishes the tool counts, settlement chains and crawl health it observes.

How does a seller get listed?

By serving x402 challenges and registering its origin with POST /api/index/register, which crawls it at once, or by appearing in the x402 Bazaar discovery listing, which the crawler re-reads every hour. Listing is free, there is no review queue, and there is no pay-for-placement.

What does crawl health mean?

A rolling success rate across recent crawls of a seller's manifest and 402 challenge. One bad hour does not delist anyone, and a new seller is not penalised for having no history. The Smart Order Router uses it to break ties and to route around sellers that are down.

My listing is wrong. How do I correct or remove it?

Write to mike@agent402.tools. Every figure here is a reading of public data - the seller's own manifest and 402 challenges, plus on-chain settlements - taken at the scan time shown, so it can go stale or fold to the wrong operator. We re-scan and correct or withdraw a row on request.

Why do tool counts and settled volume disagree?

Tool counts are what a seller advertises; settled volume is what buyers actually paid for. A large catalog with no settlements has not found buyers yet, and a small catalog with heavy volume has found exactly the right one. Both numbers are shown so you can see the difference.
